Arria10 : Remote Update IP 19.1.0 watchdog behavior
- 1 year ago
Hi,
I read this description of watchdog timer operation in Remote Update Intel® FPGA IP User Guide 2023.11.29, Table 2. Remote System Configuration Components in Intel Arria 10 and Intel Cyclone® 10 GX Devices. I think it's clear enough.The timer begins counting after the device goes into user mode. To ensure the application configuration is valid, you must continuously reset the watchdog reset_timer within a specific duration during user mode operation.
If the application configuration does not reset the user watchdog timer before time expires, the dedicated circuitry reconfigures the device with the factory configuration and resets the user watchdog timer.Regards

Obviously you are right however there are no obstacles to put once-triggered logic and call it "watchdog timer" because of necessity to repeat step with RU_RESET_TIMER not to have reflected in the documentation. It is worth to write about in the documentation to prevent questions like this one to break any doubt and guesses what the way it would work of.
